Hot top top the heels of our very first foray into the always exciting people of combined fractions, this main we’re walking to jump right earlier into the topic and also clean increase a couple of rough edges. In particular, after a fast review that the stuff we learned last time—namely what proper, improper, and also mixed fractions are and also how to revolve improper fractions right into mixed fractions—today we’re going come talk around how you deserve to turn all of those blended fractions you’ve just created ago into improper fractions. Why would you desire to execute that? That’s a an excellent question! and it’s exactly the inquiry we’ll it is in answering end the next few weeks.

You are watching: 2 3/4 as an improper fraction

## How to Turn blended Fractions into Improper Fractions

Now the we’ve had actually some exercise converting wrong fractions into mixed fractions, you might be wondering exactly how to go the various other way. In various other words, how do girlfriend undo every little thing we’ve done and convert a mixed portion back right into an improper fraction? The cheat is to start by multiply the entirety number part of the mixed fraction by the denominator of the proper fraction part. Because that the fraction 2-1/4, that means you first need to main point 2 (the totality number part) by 4 (the denominator the the proper portion part) to find that 2 x 4 = 8. Next, add this number come the numerator of the proper portion part. For 2-1/4, that method we need to include the number us got—which to be 8—to the numerator 1 to gain 8 + 1 = 9. This number is in reality the numerator of the improper fraction you’re seeking. What’s that is denominator? It’s simply the denominator of the proper fraction part the the original mixed fraction. So because that 2-1/4, it’s 4. Which way that the mixed fraction 2-1/4 is indistinguishable to the improper fraction 9/4.How around the mixed portion 4-2/3? Well, the very first step is to multiply its whole number part—that’s the 4—by the denominator the its proper fraction part—that’s the 3—to get 4 x 3 = 12. Next, add this number come the molecule of the proper fraction part—that’s the 2—to get 12 + 2 = 14. Finally, we create this number end the denominator of the proper portion part that 4-2/3—that’s the 3—to find that the mixed fraction 4-2/3 is indistinguishable to the improper fraction 14/3.

## Why go this switch Work?

At this point, this all sort of looks prefer some sort of magic trick, right? when I gain magic, I never enjoy making mathematics look favor magic…because it’s necessary to remember the it’s not! therefore let’s take a minute to number out precisely what’s walk on. First, let’s think about what a mixed fraction like 2-1/4 really means. Notification that 2-1/4 is really just another means of creating 2 + 1/4. In various other words, as we’ve talked about before, every mixed fraction is the sum of a whole number and a ideal fraction. For factors that will become clear in a moment, let’s rewrite the number 2 here as the portion 2/1. And then, simply for fun, let’s write the two fractions in the amount 2/1 + 1/4 in regards to their lowest usual denominator. I beg your pardon is…? Well, together you should inspect for yourself, the lowest common denominator that 2/1 and also 1/4 is 4.Okay, let’s currently write these fractions in terms of this lowest typical denominator. Because 1/4 is currently in terms of it, us only should worry around finding the tantamount of 2/1. One way to do that is to main point its top and also bottom by 4 to acquire the equivalent portion 8/4. For this reason the mixed fraction 2-1/4 deserve to be rewritten together 8/4 + 1/4. Since the platform of these fractions room the same, all we need to do to include them increase is include their numerators and also write the an outcome over their usual denominator. What walk this phone call us? it tells us that the mixed fraction 2-1/4 is identical to the improper portion 9/4. Look familiar? it should because it’s precisely the very same answer we obtained before. Which method that the trick for transforming mixed fractions into improper fractions yes, really isn’t a trick at all—it’s simply a speedy way of rewriting details fractions in regards to their lowest common denominator and adding them up. When again, it’s no magic…it’s math!

## Why convert Mixed Fractions into Improper Fractions?

But the concern still remains: Why perform we have to bother with any type of of this counter stuff? Can’t we just leave all the fractions in our lives alone and also let them continue to be in the same mixed or improper form that we uncover them in? as we briefly touched upon last time, the answer is that although we never ever absolutely have actually to convert from one sort of portion to another, doing so deserve to make life a lot easier. Why? due to the fact that many troubles are much less complicated to solve once the fractions in them room written in their improper form. What kind of problems? Well, unfortunately we’re all out of time for today. So the answer to that concern is walking to need to wait until next time.
